| Read Operations (Operations) | The number of read operations. |
| Real Capacity (Mebibytes) | Indicates the amount of physical storage that is allocated from an storage pool to this volume copy. If the volume copy is not thin-provisioned, the value is the same as the volume capacity. If the volume copy is thin-provisioned, the value can be different. |
| Remote Copy ID | Indicates the ID of the remote copy relationship that the Virtual Disk belongs to. |

| Secondary Writes (Writes) | The number of secondary writes. |
| Status | Indicates the status. The value can be online, offline or degraded. |
| Thin Provisioned Copies Count | Indicates the number of thin-provisioned copies. Remember: This value represents only thin-provisioned copies and is not used for compressed Virtual Disk copies. |
| Total Capacity (Mebibytes) | Indicates the total capacity of the Virtual Disk. |
| Track Destage Sector Count | The number of track destage sectors. |
| Track Destages | The number of track destages. |
| Track Read Cache Hits | The number of track read cache hits. |
| Track Read Cache Hits on Any Prestaged Area | The number of track read cache hits on prestaged areas. |
| Track Read Cache Hits Sector Count | The number of track read cache sector hits. |
| Track Read Sector Count | The number of track sector reads. |
| Track Reads (Reads) | The number of track reads. |

| Track Writes in Fast Write Mode (Writes) | The number of track writes in fast write mode. |
| Track Writes in Fast Write Mode Sector Count (Writes) | The number of track write sectors in fast write mode. |
| Track Writes in Fast Write Mode That Were Written in Write Through Due to a Lack of Memory (Writes) | The number of track writes in fast write mode that were written in write through due to lack of memory. |
| Track Writes in Fast Write Mode That Were Written in Write Through Due to a Lack of Memory sector count (Writes) | The number of track write sectors in fast write mode that were written in write through to do lack of memory. |
| Track Writes in Flush Through Mode (Writes) | The number of track writes in flush through mode. |
| Track Writes in Flush Through Mode Sector Count (Writes) | The number of track write sectors in flush through mode. |
| Track Writes in Write Through Mode (Writes) | The number of track writes in write through mode. |
